NKB-33X Gear transmitter can be used to monitor the load-regulating state of substation transformer, according to the shift position of the splitter switch into a step ratio of the analog DC voltage, by the conventional RTU or other acquisition device received, become the automatic telemetry system of the front non-power conversion equipment. The transmitter uses a variable potentiometer synchronized with the tap-changer and a three-wire bridge to transmit the voltage regulating signal to the transmitter, after the special circuit conversion, the output and the gear corresponding to the step analog current/voltage signal, each gear transmitter can measure a point contact switch, input, output completely isolated.

NKB-29S series phase angle transducer is mainly adopted to convert the real time phase angles of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.

NKB-28S series power transducer is mainly adopted to convert the real time operation current, active power, reactive power of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.

NKB-27S series DC voltage transducer is mainly adopted to convert the real time operation voltage of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.

NKB-27PD series battery voltage transducer is mainly adopted to convert the real time operation dc voltage of battery to relevant analog signals, making it readable by RTU and other signal sampling devices. It’s applicable while both device input and output are dc voltage.

NKB-27D series DC voltage transducer is mainly adopted to convert the real time operation voltage of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.

NKB-26S series DC current transducer is mainly adopted to convert the real time operation dc current of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.

NKB-26D series DIN rail DC current transducer is mainly adopted to convert the real time operation dc current of power grid to relevant analog signals in transformer substations and power stations, making it readable by RTU and other signal sampling devices.
